Twitch Link seems to be a good option to record stuff if you want an UI and dont want to use CLI. I was testing this because one anon mentioned you can download sub only vods live with this but this actually seems usefull even for normal recordings. I will add a section about this to the Arrchival guide. While setting up 24/7 recording is the best option it requires time to setup, while this is usefull to people that just want to record a quick stream that is unarchived as you just have to download and install TwitchLInk and log into your twitch account (this will then block ads in recordings/is needed for sub only vods) and thats it. While ive gotten used to using a CLI after doing this for about a year i understand why some people prefer an UI as its simpler to use for the average user.
Heres the link for it:
